Utility model content
The purpose of this utility model is that it is spherical to provide a kind of refrigeration system for technological deficiency existing in the prior art Natural gas waste cold condensing heat exchanger.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of spherical shape natural gas waste cold condensing heat exchanger, including being joined together to form in two of orbicule by demarcation plate Empty hemisphere, the demarcation plate top are provided with perforative aperture, and supercooled liquid bypass pipe passes through through-pore connection two and half The space of sphere;Left hemisphere body is in charge of with the supercooled liquid for being located at left hemisphere body lower part through corresponding aperture respectively, is located at supercooling liquid pipe The natural gas inlet pipe of top, the natural gas outlet pipe above natural gas inlet pipe and the saturated solution positioned at orbicule bottom outside The outlet section of pipe welds, and the natural gas inlet pipe is connected to natural gas outlet pipe by the intracorporal spiral element of setting left hemisphere;Right half Hole of the sphere through opening up and high-temperature gas pipe and the entrance for being saturated liquid pipe weld;Liquid is connected among the saturation liquid pipe Pump;The right hemisphere internal upper part is equipped with orifice plate, and the outlet of the high-temperature gas pipe is in the lower section of the orifice plate.
The edge of the orifice plate is formed by groove weld with corresponding position on demarcation plate, right hemispheroidal inner surface respectively It connects.
The reducing pressure by regulating flow element inlet for the outlet and refrigeration system that the supercooled liquid is in charge of connects.
The right hemisphere and left hemisphere body are the semi-spherical shape body by steel plate calendering formation.
The demarcation plate is circular steel plate.
The spherical natural gas waste cold condensing heat exchanger of the utility model, it is right using the gasification waste cold of natural gas transportation process Refrigerant liquid supercooling, high-temperature high-pressure refrigerant gas and supercooled liquid direct contact heat transfer condense, and reduce heat transfer temperature difference, refrigeration pressure Contracting machine pressure ratio reduces, and wasted work is reduced, and the performance of refrigeration system improves.
In addition, the spherical natural gas waste cold condensing heat exchanger of the utility model, sufficiently recycles the waste cold of natural gas, section About resource protects environment.
Detailed description of the invention
Fig. 1 show the structural schematic diagram of the spherical natural gas waste cold condensing heat exchanger of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
It is shown in Figure 1, spherical natural gas waste cold condensing heat exchanger, comprising:
Demarcation plate 1, supercooled liquid bypass pipe 2, right hemisphere 3, orifice plate 4, high-temperature gas pipe 5, liquid pump 6, saturation liquid pipe 7, mistake Cold liquid is in charge of 8, natural gas inlet pipe 9, natural gas outlet pipe 10, left hemisphere body 11.
The right hemisphere 3 and left hemisphere body 11 are the hollow hemispherical shape of steel plate calendering formation, and demarcation plate 1 is circle Shape plate, the circular edge of two sides are welded with the edge of right hemisphere 3 and left hemisphere body 11 respectively, are offered at the top of demarcation plate 1 Perforative aperture, left hemisphere body 11 offer supercooled liquid respectively and are in charge of 8, natural gas inlet pipe 9, natural gas outlet pipe 10 and for will be right The intracorporal saturated liquid of ball is discharged to the aperture that passes through of entrance of the intracorporal saturation liquid pipe 7 of left hemisphere, and respectively be mounted on pair Answer the supercooled liquid in aperture be in charge of 8, natural gas inlet pipe 9, natural gas outlet pipe 10 weld, natural gas inlet pipe 9, natural gas outlet pipe 10 it Between be connected with and bend helically shaped spiral element, the natural gas inlet pipe 9, natural gas outlet pipe 10 are connected, to realize day Right flow of air exchanges heat, and is offered respectively on the right hemisphere 3 for introducing refrigeration system discharge high temperature and high pressure gas To right hemisphere it is intracorporal connection high-temperature gas pipe 5 and be saturated liquid pipe 7 outlet section aperture, and respectively be mounted in aperture High-temperature gas pipe 5, be saturated liquid pipe 7 outlet section welding.
Wherein, the surface of the orifice plate 4 be equipped with multiple perforative apertures, edge respectively with demarcation plate 1 and right hemisphere The groove of corresponding position on the inner wall of body 3 welds.
Wherein, the supercooled liquid bypass pipe 2 passes through the through-pore of demarcation plate 1, is connected to the space of the two cerebral hemispheres.
